Question

我在本地开发环境中的Docker上使用MongoDB v3.6.2实例。将MongoDB.Driver NuGet程序包从2.7.0升级到2.7.1，使以下代码引发异常。

string connectionString = "mongodb://localhost:27017/foo";
var database = new MongoClient(connectionString).GetDatabase("foo");
var collections = database.ListCollectionNamesAsync().Result.ToListAsync().Result;

我希望收集的列表像往常一样，但是会引发以下异常。

System.AggregateException: One or more errors occurred.

它在具有.NET SDK v2.1.403的Ubuntu 18.06 x64计算机上运行。

Answer 1

我知道这不是答案，但我缺乏评论的声誉。我也有同样的问题。今天早上，我将驱动程序更新为2.7.1。我在Windows中看不到问题，但是在Linux docker容器中运行应用程序时确实看到了问题。

更新：2.7.2已发布，它为我解决了该问题。

Answer 2

我有同样的问题。他们刚刚发布了2.7.2。它解决了。

将MongoDB.Driver从2.7.0升级到2.7.1后，连接超时
